Authentication method and authentication system

1. A method for authentication and/or identification of persons, objects or service systems by security features, comprising the steps of: a. providing a material, a structure, a substance or a composition for the generating of a security feature, b. assigning this material, the structure, the substance or the composition or parts thereof or an image of these to a specific person, an object, a medium or a service system, c. capturing the image of this material, the structure, the substance or the composition and storing in a memory device at a first time point, d. comparing the image of this material, the structure, the substance or the composition with the image stored in the memory device, wherein the material, the structure, the substance or the composition or the image of these is actively changed by a physical, or mechanical impact or feature, so that the resulting structure or property is unpredictable, and that at a later time point the image of the material, the structure, the substance or the composition is captured again and the thus obtained current image is compared with the stored one in the storage device, wherein the person and/or object and/or the medium and/or the service system is then authenticated positive by the security feature, if the material, the structure, the substance or the composition vis-à-vis the image stored in the storage device or parts thereof has/have at least partially changed between the two time points, wherein the change of the security feature comprises a mechanical impact, a stretching, a drawing, of a material, a mechanical merging of surfaces, the impact of a flexible substrate on the overlying surface or the storage of voids and or particle in a material or substance, and wherein the material, the structure, the substance or the composition continuously changes.

2. The method according to claim 1 , wherein the material, the structure, the substance or the composition change only dynamically, when it comes to an authentication request.

3. The method according to claim 1 , wherein the image of the material, the structure, the substance or the composition is changed after capturing by a dynamic factor regardless of whether the material, the structure, the substance or the composition itself has already changed.

4. The method according to claim 1 , wherein before, during or after the authentication request, the image stored in the memory device or parts thereof is/are replaced by the current image.

5. The method according to claim 1 , wherein the material, the substance, the composition or the structure comprises cracks or recesses, which increase during stretching or pulling apart.

6. The method according to claim 1 , wherein the material, the substance, the composition or the structure comprises at least two surfaces, which develop different from each other.

7. The method according to claim 1 , wherein the material, the substance, the composition or the structure consists of a surface, which is coated with a protective coating, such that the structure or feature of this surface is then changed, if the protective coating has been either removed or deactivated.

8. The method according to claim 1 , wherein the material, the substance, the composition or the structure contains particles or voids, whose arrangement, position and geometry develop dynamically.

9. Authentication system for performing the method according to claim 1 , comprising: a local or centralized storage device for storing an image of a security feature in the form of a material, a structure, a substance or a composition, wherein the stored security feature is assigned to a person, an object, a service for service provision or a medium, an interrogator to retrieve a current image of the security feature, a data comparison means for comparing the retrieved image with the image of the material, the structure, the substance or the composition stored in the memory device, wherein the material, the structure, the substance or the composition consist from changing, unforeseeable features or structures, have unpredictable features or structures, which change continuously, and wherein the change of the security feature comprises a mechanical impact, a stretching, a drawing of a material, a mechanical merging of surfaces, the impact of a flexible substrate on the overlying surface or the storage of voids and/or particle in a material or a substance.

10. The authentication device according to claim 9 , wherein a dynamic factor is provided which effects a dynamic change in the property or the structure of the material, the structure, the substance or the composition wherein the dynamic factor changes itself dynamically between two time points.

11. The authentication device according to claim 9 , wherein the material comprises cracks or recesses which increase in case of an extension or a contraction of the material, such that the outer image changes.

12. The authentication device according to claim 9 , wherein the rigid geometric elements in the security element are incorporated into the material, such that in case of elongation of the material, individual structures, cracks or recesses in the material become visible.

13. The authentication device according to claim 9 , wherein the security feature consists of two different surfaces, wherein one surface exhibits a textured surface with spikes and edges, while the other surface is an untreated surface, such that the two surfaces are mechanically so mergeable that the spikes and edges of the structured surface project, rub, or press in the untreated surface.

14. The authentication device according to claim 9 , wherein the security feature has a rigid and a flexible substrate, wherein the rigid substrate does not alter the overlying surface, while the flexible substrate leads to a change in the structure of the overlying surface.

15. The authentication device according to claim 9 , wherein the security feature comprises a structured surface, which is covered by a protective coating, which causes that the underlying structure does not change, such that the surface of the dynamic security feature is covered by an activation coating, which changes the underlying structure.

16. The authentication device according to claim 9 , wherein the security element comprises particles with individual features that are present in a material or substance, wherein the material includes voids and/or particles, such that the voids and/or particles can be changed in their shape or position.
